Yeah, I'm kinda curious about this, since my main distributor just restocked on all the old chapter packs, so I was able to pick up all of the ones from the first cycle for a player who was in Korea when they first came out. They were for Game of Thrones, but I know they also got the fist cycle of Cthulhu in as well, so I;m not sure why your local store can't get them. Not sure what distributor they use, so that might be an issue (it seems that some distributors only sell them in batches of 6, which is a "display," but I know many will sell them to stores 1 at a pop.
